ARTICULATED ENGINE.

Application filed February 3, 1913.

To aZZ wit-0m it may concern:

Be it known that. I, Lonnv TV. BARGER, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Articulated Engines, of which the following is a full, clear, and exact description.

My invention relates to the supporting structure for the gearing used to transmit power to the driving-wheels of the truck of an articulated engine.

The object of said invention is to provide a resilient structure for supporting said gearing, which is carried by the truck; which will permit the independent vibrations of the driving-wheels and trucle frames; which will not afiect the connection between the actuating mechanism of the engine and the crank-shaft, and which will always maintain the relative position of the gearing for imparting the motion of the crank-shaft to the driving-wheel axle. These and other advantages are accomplished by'my improvements, substantially as hereinafter fully described, and as particularly pointed out in the claims.

In the drawings: Figure lis a plan view of one end of an engine-truck of an articulated locomotive embodying my invention showing one side portion in horizontal section. Fig. 2 is a vertical longitudinal section thereof taken on dotted line 2, 2, Fig. 1. Fig.3 is a vertical transverse section of said truck taken on dotted line 3, 3, Fig. 1, showing one side of the structure in transverse vertical section.

Referring to the drawings, A, A, represents the side-frames of a pedestal truck that supports the engine; B represents the driving-wheel and B the axle therefor, and C represents the journal-boxes which are provided with suitable shoes and wedges c, that engage the pedestal jaws a of the side frames of the truck, in the usual manner. At a suitable distance from the axis of the driving-wheel, and, preferably, at a point remote from the wheels of the truck, the side-frames A thereof are provided with another pedestal a, and the jaws of this last-mentioned pedestal are engaged by the shoes and wedges d of a suitable journalbox (Z, in which latter a sleeve 6 is journaled that provides bearings for the transverse crank-shaft-D. The inner end of journal Specification of Letters latent.

box (Z is tubular and extends inward beyond its bearings a suitable distance and is journaled in stationary bearings in the vibratory ends of auxiliary side-frames E.

About its center of length the crank-shaft is provided with a suitable gear 2, and this gear meshes with and imparts its motion to an idle gear 3, which latter engages and drives a large gear A mounted upon the driving-axle B about its center of length. The shaft on which the idle-gear 3 is mounted is jo-urnaled in suitable bearings 6 in the upper raised central portion of the auxiliary frames E and the bearings 6 extend inward toward each other. Below bearings 6 said frames E are connected by a cross-beam 7, and they are also connected by an arched bridge 8, the ends of which latter are connected to and spring from the side of bearings 6 nearest the car-axle. The central portion of cross-beam 7 is of substantially I-cross-section, and on either side of the plane of the train of gears 2, 3 and 4, its end portions are spread laterally to enable its extremities to present a large bearing surface to the auxiliary frame E, to which they are bolted or otherwise suitably secured. The bridge 8 passes in front of the idle-gear, and its under edge is recessed to provide clearance and protection for the engaging portions of gears 3 and 4.

The journal-boxes C have inwardly extending cylindrical portions upon which the ends of the auxiliary frames E, opposite the crank-shaft, are loosely mounted, and immediately above journal-box d, frames E are each provided with an upwardly projecting lug 9 to which the downturned ends of a yoke or hanger 10 are suitably secured by a bolt or pintle 12, substantially as shown in the drawings. Between these downturned ends, the yoke 10 extends horizontally from frame E on one side to frame E on the other side of the truck, and the center of length thereof is provided with an upwardly projecting vertical web 13, the upper edge of which has a horizontal lug 20 that extends, preferably, in the direction away from the gear 3.

A transom 14 connects side-frames A, in substantially the same vertical plane as the yoke 10, and the ends of this are seated upon and secured to the upper edge of said side-frames. The lower edge of this transom between. side frames A is, preferably,

horizontal and at about its center of length it is provided. with a horizontal flange 15 that extends toward the gear 3. The central portion of the upper edge of said transom extends upward and is highest at its center of length Where it is provided with a horizontal flange 16 that corresponds with its lower horizontal flange When properly assembled, the lug 20 of the yoke lO'Wlll project between the upper flange it) and the lower flange 15 of the transom, and will be retained in this position so that it may vibrate up and down by means of a vertical pin or bolt 17, which latter extends down through a suitable perforation in the upper flange 16 of the transmit lug 20 of the yolre and the lower flange 15 of the transon'i, and coil-springs l8 and if), respectively, surround said bolt 17 between said flanges and lug, and thus make a resilient connection between the yoke and transom.

From the foregoing description. it will be apparent that tho crank-sh i the jour'nah box thereof, the ends of the auxiliary trainee in which the gear-shaft is iournaled. and the gears 2 and 3 for transmitting the motion of the crankshaft to the large gear on the driving-u'l ieel axle are all suspended from transom l t in such manner that any vibration thereof, due to the travel of the truck over the rails, or to the action of the mechanism that imparts motion to the crankshaft, or to both, will be accommodated by the yielding connection between the yoke 10 and the said transom and will allow of that flexibility of connection between the aci:u ating mechanism ofthe cranl-z-shaft and the (TlllVlIlgfiVllQGl axle necessary to insure the practical and satisfactory operation of this part of an articulated engine to Which my improvements are particularly adapted to be applied.
